VIOLET-RAY GENERATOR.

Application filed January 31, 1923.

To all 'whom t may concern Be it known that l, BnNNo FREDERICK JANoKn, acitizen of the German Republic, and residing at Number 1406 PacificStreet,

in the borough of Brooklyn, city and State of New York, have inventedcertain new and useful Improvements in Violet-Ray Generators, of whichthe following is a specilication.

This invention relates to violet ray generators of the applicator type,that is, designed primarily for therapeutic use, and aims to provideimprovements therein.

The invention provides a device of the character referred to, of simpleconstrue` tion, capable of ready and economical manufacture, and hencecapable of sale at a popular price.

An embodiment of the invention is illustrated in the accompanyingdrawings, in

which- Figure 1 is a longitudinal sectional view of the generatorshowing a so-called applicator connected thereto.

Fig. 2 is a view partly in section and partly in elevation of a spool orframework, in which the various electrical parts are convenientlymounted.

F ig. 3 is a diagrammatic view showing the electrical construction andarrangement.

Referring to said drawings, numeral 10 designates a spool or framework,having a socket or other means of attachment 12 in one end, adapted tohold an electrode 14 i of the applicator type therein and wit-hin whichis generated the violet ray to which the therapeutic action of thedevice is due. This spool 10 is adapted to lit within aftube or sleeve16, and the spool is conveniently formed with a head 18 at one end,which closes one end of said tube, said head 18 being preferablyslightly tapered as indicated at 19, so as to enter the tube easily andmake a tight fit therewith, said head also being conveniently formedwith a shoulder 20 against which the end of the tube 16 abuts. Behindthe head 18 the spool is of reduced diameter, as indicated at 25, 26, toafford space within the tube 16 for the primary and secondary windings27, 28 of the high-tension transformer or spark coil 30, and for achoke-coil or inductance 32 and a condenser 34. The end 37 of the spoolis conveniently of enlarged diameter, correspending to the insidediameter of the tube Serial No. 616,091.

16, and serves to support the said tube, and also toform a support orbase for the interrupter or sparking electrodes 40, 41. The spool 1() isalso preferably provided with an annular enlargement 44 about midwaybetween the head 18 and the opposite enlargement 37, and of a diametercorresponding to that of the tube 16, which serves to support the middleportion of said tube and divides the space between the ends of thespool.

On the end enlargement 37 there is conveniently provided two posts 46which support a bridge piece 47, and preferably also a disc 48, ofinsulating material. The sparking electrode 41 is supported by saidbridge piece 47, the said electrode being preferably mounted on athreaded rod 49 by means of which the distance apart of the electrodes40, 41 may be adjusted and the intensity of the violet ray controlled.The tube 16 preferably extends beyond said disk 48, so as to close theadjacent end of said tube and consequently enclose the parts on the endportion 87 of said spool.

The spool 10 is preferably bored at each end, asindicated at 50, 51, theformer serving for the receptio-n of an iron core for strengthening themagnetic effect of the choke-coil 32. The recess 51 serves for receivinga tang 54 on a conducting thimble 55, 4and connection of the end of thesec ondary winding 28, to the tang 54 is conveniently made through asmall hole 57.

The electrical arrangement is conventional, the secondary 28 beingconnected to the applicator 14, at one end as indi cated at 60, Fig. 3,and grounded on the primary 27, as indicated at 61. The primary isconnected to the lead wire 70 through a conductor 71 on one side, and tolead wire 73 through choke-coil or indue tance 32, interrupter orsparking electrodes 40, 41, and conductor 74 on the other side. Thecondenser 34 is placed in shunt with the primary 27 by wires 7G, 77 7 8leading to conductor 71', and to the interrupter 40, 41. An oscillatorydischarge is produced between the sparking electrodes 40, 41, which setsup oscillations in the primary 27, thereby inducing high-tensioncurrents in the secondary 28, thereby producing the violet* raydischarge in the rareiied applicator tube 14.

The inventive idea may receive other embodiments than that hereinspeciiically illus` trated and described.

What I claim is:

l.v A violet ray generator, comprising a spool yor frame, havingportions of reduced diameter, coils and a condenser on said reducedportion, and a tube adaptedv to slip onto said spool and cover saidcoils and condenser, said spool having portions having a diametercorresponding to that ot said tube` for supporting the same.

:2. A yviolet ray generator, comprising a spool or i'rame,.havingportions of reduced diameter, coils and a condenser on said reducedportion, and a tube adapted to slip onto said spool and cover said coilsand condenser, said spool having portions having a diametercorresponding to that ot said tube for Supporting the same, one ot saidtube-supporting portions constituting a head and having anapplicator-socket therein. y

3. A violet ray generator, comprising a spool or frame, having portionsof reduced diameter, coils and a condenser on said reduced portion, anda tube adapted to siip onto said spool and cover said coils andcondenser, said spool having portions having a diameter corresponding tothat ot said tube for supporting the same, said tube y being anopen-ended tube ol: substantially uniform diameter.

4. A violet ray generator, comprising a spool or frame,'having portionsotreduced diameter, coils and a condenser on said reduc-ed portion, anda tube adapted to slip onto said spool and cover said coils andcondenser, said spool having portions having a diameter corresponding tothat ot said tube for supporting the same, said tube being an open-endedtube of substantially uniform diameter, one of said tube-support-` ingportions constituting a head and having; an applicator-sockettherein.
